Increased B Cell-Activating Factor Expression Is Associated with Postoperative Recurrence of Chronic Rhinosinusitis with Nasal Polyps

Figure 4

Histopathology and BAFF protein expression in the tissue among three groups. (a–c) Representative H&E images from HC, CRSsNP, and CRSwNP. (d–i) Representative IHC staining of BAFF in HC, CRSsNP, and CRSwNP (magnification, 200x and 400x). BAFF: B cell-activating factor; H&E: hematoxylin and eosin; CRSwNP: chronic rhinosinusitis with nasal polyps; CRSsNP: chronic rhinosinusitis without nasal polyps; HC: healthy control; IHC: immunohistochemistry.
